The 7mm-08 Remington is a rifle cartridge that is almost a direct copy of a wildcat cartridge developed around 1958 known as the 7mm/308. As these names would suggest, it is the .308 Winchester case necked down to accept 7 mm (.284) bullets with a small increase in case length. Of cartridges based upon the .308, it is the second most popular behind only the .243 Winchester. However, the .308 is more popular than both. In 1980, the Remington Arms company popularized the cartridge by applying its own name and offering it as a chambering for their Model 788 and Model 700 rifles.
The popularity of the cartridge means there is a fairly wide selection of factory loads, making it a choice even for those who do not handload. Bullets weighing from 100 to 195 grains are available. Bullets in the 130-150gr range will suit most hunting applications while long range shooters will opt for the heavier bullets to take advantage of their higher ballistic coefficients. Depending on construction, bullets of 154 to 195gr can also be used in loads suitable for medium and larger game or target purposes. Medium burning rifle powders usually work best in the 7mm-08.
With the wide range of bullet weights available, the 7mm-08 is suitable for "varminting, game-hunting, Metallic Silhouette, and long-range shooting." It is also suitable for plains game." For long-range target and metallic silhouette shooting, the "plastic-tipped 162gr A-Max has proven to be very accurate with a 0.625 BC (G1). This A-Max bullet, and the 150gr Sierra Match King, are popular with silhouette shooters."
The 7mm-08 Remington works in most hunting environments, including dense forest areas and large open fields. It has a flatter trajectory than the .308 Win. and .30-06 Springfield at similar bullet weights because the slightly smaller-diameter 7mm bullet generally has a better ballistic coefficient (BC), and is thus less affected by drag and crosswind while in flight. Its trajectory is comparable to the .270 Winchester.
